Embodiment Construction

[0032] Below, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not constitute limitations to the present invention:

[0033] The air conditioner of the present invention can realize its function only when it is powered on and the compressor is powered on. First of all, when the air conditioner leaves the factory, the designer simulates the dirty air filter of the indoor unit to the extent that it needs to be cleaned within the range of common use environments, and obtains the disk temperature of the indoor heat exchanger in the cooling mode of the air conditioner in this state. The tube temperature Ta and the coil temperature Tb of the indoor heat exchanger in heating mode are input into the program of the indoor electric control system, where Ta is used as the cooling alarm temperatu...

Abstract

The invention discloses an automatically-reminding method for dirty and blocking of a filter screen of an air conditioner, comprising the following steps: step S1) of presetting a refrigeration alarm temperature Ta and a heating alarm temperature Tb in an air conditioning system; step S2) of judging a operation mode of the air conditioner; executing a step S3 if the operation mode is a refrigerating mode; executing a step S4 if the operation mode is a heating mode; step S3) of detecting temperature T of a coil of an indoor heat exchanger, and comparing T with Ta; if T is not greater than Ta, forcing the indoor heat exchanger to operate at high speed by a period of time t1, and then detecting the temperature T of the coil again; if T is not greater than Ta, outputting a filter screen dirty and blocking signal; step S4) of detecting the temperature T of the coil of the indoor heat exchanger, and comparing T with Ta; if T is not less than Ta, forcing the indoor heat exchanger to operate at high speed by a period of time t2, and then detecting the temperature T of the coil again; if T is not less than Ta, outputting the filter screen dirty and blocking signal. According to the invention, users can be reminded to clean the filter screen in time so as to provide necessary support for high-efficiency operation of the air conditioner, and therefore, use of the air conditioner is more energy-saving.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically relates to an air conditioner and an automatic reminder method for dirty and clogged filter screens thereof, which are used to remind users to clean the filter screens so that the air conditioner can operate efficiently. Background technique [0002] The air conditioner filter is a device that filters the air to prevent impurities such as dust from entering the heat exchanger. However, after the air conditioner is used for a period of time, impurities such as dust will be covered on the filter screen, reducing the air intake of the indoor unit, thereby affecting the cooling or heating effect of the air conditioner. [0003] At present, the air conditioners sold on the market do not have the function of reminding the filter screen to be dirty and clogged, but only write words such as "users are required to clean the filter screen regularly" on their product manuals. ...
